An Orthodox Jewish man who pleaded guilty to raping a young Brooklyn boy in a ritual bath was sentenced to five years behind bars today, as his victim’s mom called him a “monster of an animal.”

Meir Dascalowitz, 29, pleaded guilty to sexual abuse in Brooklyn Supreme Court last month for forcing himself on his mentally-disabled victim.

“We cried a lot and had and still have endless sleepless nights,” the victim’s mother said in court before Dascalowitz was sentenced. “What this monster of an animal did to a precious diamond is unforgivable.”
